Nelson Mandela’s Death: Barack Obama Tribute

I've just prepared this worksheet based on Obama's speech on Nelson Mandela's death to work with one of my students today. It should be precedeed by some brainstorming on his life.
You can find the video here http://www.bbc.co.uk/news/world-africa-25250278 On this same link there's another very interesting video on the life of Mandela, it could also be used with a little preparation. Hope you find it interesting.
